Explanation:
Microspheres were spherical bodies with metabolic abilities that could successfully sustain their existence. However they did not contain any genetic material. Which means that they could not replicate or pass off their parts to their successive generations.
But they had no way to evolve since they could not pass off any genetic material to their offspring's. This is why RNA came into existence. RNA enabled an Organism to store its genetic material into nucleic acids, that could be passed on to generations to come. This is also how they could evolve into more complex organisms.

Question 10: True Question 11: Competition and Variation
Explanation:
Natural Selection is when the animal with the best survival rates gets the right to mate. Every species wants to survive and by letting the animals with the best traits reproduce, it ensures their survival. This, of course, happens naturally.
Competition is to show whose fit and whose not and variation increases the chance of their survival. For example, if a whole species was exactly the same if one died of a disease then all of them would, because they would have the same immune system. But if there is variation, one might be vulnerable to the disease but the other might have protection from it. Meaning it could pass those genes to offspring because it was fit.
Hope this helped :)
Answer:
perform different functions for the organism
The main function of the flower stock is transporting food in the form of water and nutrients to different parts of the plant with the help of xylem and phloem. Xylem helps in transporting cells that help in carrying water and minerals from the roots while phloem transports food in the form of sugar to all parts of the plant. The stock also helps in keeping the the flower steady above the plant folliage. This directly helps in the process of pollination of the plant. The flower that is held steady above the folliage attracts bees and other insects through which it continues the process of pollination.
They would have a competitive relationship since they are in the same class
